- THREAD-CUTTING LOUIE-TEMPLE.

Specification of Letters Patent.

Application filed August 10, 1912. Serial No. 714,335.

To all whom it may concern:

Be it known that I, EDWARD A. CUNNIFF, a citizen of the United. States, and resident of New Bedford, county of Bristol, State of Massachusetts, have invented an Improvement in Thread-Cutting Loom-Temples,-of which the following description, in connection with the accox'npanying drawing, is a Stimpson, the severing of the thread being effected by the co jperation of relatively fixed and movable blades mounted on the temple head, the movable blade normally projecting beyond the temple head. lVhen the lay heats up a depending heel on said blade is struck, and the blade is first rocked to thread-engaging position and then it is moved bodily adjacent the fixed blade, to sever the thread with a shear cut. In certain cases trouble has been experienced with such temples, resulting in breakage ofthe cutting device, and in other cases the reed may be injured or the thread may be out at the wrong time In my efforts to overcome these troubles I have found that they can be obviated altogether by the provision of means to regulate the distance to which the movable blade projects, and my present invention has for its object the production of a thread cutting temple having provision for adjusting or regulating the position of the movable cutting blade when the latter is projected. a K I The various novel features of my invention will be fully described in the subjoined specification and, partieular-lypointed out in f'tli e follo- ,ing claims.

Figur', 1 is an outer side elevation of a thread cutting loom temple embodying my present invention, with the movable blade projected its full distance, but showing the regulating or adjusting means therefor; Fig. 2 is a similar view, but showing the movable blade adjusted for weaving heavy pick goods,when the templeis set as near as possible to the fell of the cloth; Fig; 3 is a View similar to Fig. 2, but the movable blade is shown as depressed and just about to be moved bodily toward the front of the loom; Fig. ,4 is a perspective view of the adjustable stop for the movable blade.

pending from the pod, the shank Dot the temple mounted slidably in the stand, the upright cutting blade E fixedly mounted in the temple head, see dotted'lines, Fig. 1, Y

and the cooperating movable cutting blade F, having the depending heel G and mounted'torock and also to be moved bodily, and the projecting spring H, may be and are in general all substantially of well known and usual construction, the pod having the usual notch I for the reception'of the thread of filling to be cut. Ordinarily the end ofthe blade F adjacent the depending heel has a lateral ear thereon to constitute a stop, the

stop engaging the face of the temple head toward the front of the loom when the said blade is projected, to thus limit the spring induced movement of the blade, Such arrangement permits the blade to be positi oned substantially as shown in Fig. 1 when projected, the hooked endthereof bein in readiness to descend. and engages. thread of filling at'some little distance beyond the notch I, andthen to draw such thread against the fixed blade E. In ordinary weaving the project-ion of theblade shown in Fig. l is not objectionable, for the fell of the cloth, indicated at J, is some distance beyond the temple, and the cutting blades cannot operate too soon. WVhen, however,

heavy pick goods are being woven, it is necessary to move thetemple as near as possiw ble to the fell, to keep the selvage threads.

from breaking, and. the projected blade is very near the reed on the beat up. Ifthe blade strikes the reed the latter is spoiled and the blade will almost invariably be moved to cut the fillingthread at the me time."

Again, if a warp thread fails and the shuttie is at the replenishing side of loom,

when the weaver moves the lay for-ward to even the harnesses the filling thread is beneath the movable cutting blade, (because of the close set-tin of ti to the fell} so that l the thread will becaught and cut by the out of the shuttle-eye is long enough, howoperation of the hlagles. .The filling hanging ever, to tilt the usual fork, and the loom will continue to run and will make one or more faulty picks until the trouble is'noticedl I overcome these objectionable features by providing a stop for the movable blade which can be regulated or adjusted to vary the extent to which the blade can. be pro jected. To this endI lengthen the frontward end of the blade F,'at 1, and mount thereon a stop, shown separately in Fig. 4

as comprising a fiat base 2 having a longitudinal slot 3 and a lateral lug 4 having a convexed face 5. The stop is secured to the vious that if the blade were positioned as in- Fig. 1 and the temple set up close to the fell extension 1 of the bladeby a suitable screw 6, the shank of which passes through the slot- 3 and into a threaded hole in the extension of the blade. As shown in the drawing the face 5 of the stop lug is turned toward the adjacent face of the temple head, and when the heel G is struck by the lay the blade F first rocks as the face 5 turns on the 25' adjacent part of the temple, and then the blade is moved frontward bodily.

Referring now to Fig. -l I have shown the stop as set to permit the full projection of the blade F by the spring H,-but in Figs. 2 and 3 I have shown the stop set so that ,when the blade is controlled thereby several picks must be made before the blade can engage or cut the filling thread. In Fig. 2 the temple is shown as adjusted very close to the fell J of the cloth, as would be the case if heavy pick goods werebeing woven, and accordingly the blade stop is adjusted toward the hooked end of the blade F, so that the latter cannot project so far beyond the temple head. This is made clear by a comparison of Figs. 1 and 2, and itwill be ohthe filling would inevitably be cut when starting the loom after a warp 'fault, as hereinbefore set forth. Now when the'temple is set close to the fell, as in Fig. 2, and the blade stop is adjusted as therein shown, the downward movement' of. the blade into the position shown in Fig. 3 will cause the blade to clear the filling thread, and the latter will not be cut. In fact, when the stop is so adjusted, the filling thread cannot come within the control of and be severed by the cutting blades until two or three picks have i been made. The range of adjustment is between the positions shown in Figs. 1 and 2, and is suflicient for practically any setting of the temple with relation to the fell of the cloth, and the adjustment can roe-made very quickly and readily. This adjustment of the movalile blade obviates-injury to the reed, for by diminishing the projection of the blade beyond the temple head the bodily retracting movementof said blade will begin before it can strike the reed. By the adjustment of the movable blade I am onabled practically to maintain the latter in a certain relationship to a given fixed point whether the temple itself be adjusted frontward orba.ckward, as will be apparent. There is another advantageresulting from the adjustability of the movable blade. Usu-'.

allythe front of the lay has attached to it a piece of leather so located that the heels G and"C will be hit successively by the leather on the beat up, but sometimes a lateral setting of the temple will result in moving the blade heel G beyond the leather, or the latter wears unevenly. Then on the beat up the heel G will be engaged, so that -when it is struck it not only retracts theblade F but the said blade andits heel must take the entire strain or the major part of it, of moving the entire temple head, and as a result the blade heel is broken off. By

the adjustment of the blade herein provided for this objection is avoided, for if the leather wears unevenly, orthe lateral setting of the temple takes .the blade heel beyond the leather on the lay, the fault can be compensated for by adjustment of the movable blade, and thereby its heel is set forward, or toward the front of the loom.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1.. A loom temple having a head pro vided with relatively fixed and movable blades to part the filling, a spring to project the movable blade, a stop on the latter to cooperate with apart of the temple head and thereby. limit spring-induced movement of the blade,- and menas to .hold the stop in difterentpositions on the blade.

2. A loom temple having a head provided with relativelv fixed and movable blades to part the filling, a spring to project the movable blade, an extension on the 1 forward end of the blade. a stop mounted adjustably on the extension, to coiiperate with an adjacent part of the temple head and limit the spring-induced movement of the blade, and means to hold the stop in adjusted position upon said blade extension. 3. The combination in aloom temple having a head provided with a fixed blade, and a cotiperatingmovable blade, to cut the fill ing thread, said movable blade having a heel adapted to be struck to efi'ect rocking and bodily retractive movement of'the blade, and a spring to project the latter, of means to vary the extent to which the blade can be projected by the spring.
